For CT....
Ron's Guitars in Groton has a decent selection of Mesa & SWR bass stuff....
G Guitars has a nice selection of Aguliar, Eden, and usually a FX-1 in stock....
I havent been to East Coast Music Mall (Danbury) in a while, but they usually had a good selection new & used.
If you want a good laugh, go to Banko's in Ansonia~ the place is crammed full of stuff (guitars hanging from every inch of the 8' ceiling) and really hard to manuver through.
My favorite non-music places to shop are Superior pawn in New Haven, TC's pawn & gun in Waterbury, and there were a couple of other seedy shops in Bristol.
Didnt you pick up a Nemisis combo recently?!?
